How can/should I go > about improving network performance? I've not tried the ping but I'm seeing exceptionally poor performance on G4s to FreeBSD. The G4's can ftp to each other at about 8-9MB/sec, as can the FreeBSDs. They are on a Cisco 2948 switch. But ftp from BSD to G4 is in the order of 20-40KB/sec while G4 to FreeBSD is about 1/2 that. This was first noted by a client who has a G4 in our rack and have a very large flash file on their front page. I've also heard annecdotal reports of slow G4 to MS machines too. But not everyone has this and I can't seem to find an answer. And I have NO problems with pings. Just data transfer. One G4 runs high load as shown under very little CPU available under top, while the other is far less stressed.
